His art project, The Good News, places posters of happy news (often with puns) around the city to brighten people's day.

He told Mashable he started the project after seeing a missing dog sign that said "STOLEN."

"It's quite sad when someone loses a pet," he said. "The idea popped into my head that by simply adding 'Our Hearts' at the bottom of the poster, it would completely change its meaning and turn into something positive."

One man in Gaza probably wishes he had been told that before he let an original Banksy go for a measly $175.

Rabie Dardouna, who owned the door and rubble which Banksy adorned with a piece called “Bomb Damage” (above), pawned it off to a man named Belal Khaled for just the value of the metal. His house was destroyed during an Israeli attack last year.

“I did not know that it was this valuable. I heard it can be sold for millions,” Dardouna told The Guardian. “Now I want the door back.”

Khaled claims he only purchased the door to “protect its artistic value” and isn’t looking to make money off the deal.

He added that he might one day consider displaying it in a gallery to “speak about the suffering of Gaza and the agonies of war.”

Parisian street artist Etienne Lavie took garish public advertisements and replaced them with works of classical art, invoking the history of the city and French art culture as a whole. Check them out here!
